IMPROVEMENT IN PLANES.

Specification forming part of Letters Patent No. 33,240, dated September 10, 1861.

' To all whom it may concern:

end ot' this stock is secured a plate l, made of metal. These plates are both provided with circular-formed slots 2 represents a bent arm, which is secured through its angular portion to the planestock by means of a screw 5. This arm turns upon the screw 5 as a center. When the screw is tightened the arm is made fast to the stock. One end of the arm is provided with a slot 4.. A set-screw 6 passes through this slot and also through the slot 3. This screw 6 is so arranged as toallow the arm 2te partially revolve when necessary and also to station it at any desired point. By means ot' ther than it could otherwise do, as is clearly evident, andis thus enabled, with the help of the guide 7, to form a miter.

7 is the guide upon the end of the arm for holding the plane to its position at any angle at which it is set. This guide, together with the arm 2, may be removed at any time by simply removing the screws 5 and 6, thus making the common plane of it. The end plates with this attachment may be used upon any common joiners plane.

I claim- 1. The combination of the arm 2, provided with slot 4, with the slot in plate l for the purpose of extending the slot .3 to forma miter.

2. The combination ofthe guide 7, the arm 2, the slotted end plates 1 and the screws 5 and 6, when the several parts are constructed and arranged in the manner herein set forth.
